SAMUEL B. GHAFFEY, OF SUPERIOR, WISCONSIN.

CLOSURE OPELRATOB, .AND LOCK.

Application led May 1,

To all whom t may concern.'

Be it known that I, SAMUEL B. CHAFFEY, a citizen of the United States,residing at Superior, in the county of Douglas and State of Wisconsin,have invented certain new and useful Improvements in Closure Operatorsand Locks; and I do declare the following to be a full, clear, and exactdescription ot the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple andinexpensive, yet an easily operable and eli'ective device for operatingscuttle doors, transoms `or other closures and locking them, theconstruction ot the present form of my invention, being such as to lockthe closure either in an open position or in a closed position.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawing. Figure 1 is a sectional viewof a closure and its frame, showing the application of one form of myinvention positioned to hold the closure shut.

Figure 2 is a duplicate of Fig. 1 with the exception that it illustratesthe closure held in open position.

Figure 3 is a sectional view on line 3-3 of Fig. 1. p

Figure 4 is a similar view on line 4 4 of Fig. 1.

Figures 5 and 6 are views similar to Figs. 1 and 2 but showing adifferent form of construction.

In the drawing above briefly described, the numeral 1 designates apivoted closure carried by a suitable trame 2. Pivoted at 3 to thistrame or to any other desired stationary part, is an operating memberwhich may have any desired configuration, such as the disk 4 shown inFigs. 1 to 4 or the bell crank 4t disclosed in the other iigures. Thisoperating member may either have a handle 5 carried directly thereby orsuitable operating means may be connected to said member and extend to aremote point.

A link 6 has its inner end pivoted at 7 to an olif-center part of the-operating member 4 or 4a and the outer end of this link may beconnected. with the closure 1 in any de- 1923. serial No. eaasa.

sired manner, for instance by pivoting said link at 8 to a bracket 9which is secured to the closure 1. y

It will be seen from the above that turning the operating member in onedirection will open the closurel, while turning said member in the otherdirection will close said member and I make provision for limiting themovement of the operating member to such an extent as to permit the linkto snap slightly past dead center to lock the closure. In the presentshowing, a stop 10 is mounted on the trame 2 or on some other adequatestationary part, in the lateral path ofthe link 6 and this link contactswith the stop both when the closure 1 is shut and when it is open, thepivot 7 being slightly beyond dead center in either of these positions,so that the closure is positively locked against movement unless theoperating member 4 or 4a is turned.

If desired, I may provide supplemental means to hold the operatingmember in an intermediate position or a number of such positions. Forinstance, the disk 4 may be provided with spaced peripheral notches 11,to be engaged by a suitable latch bolt or the like 12.

By employing the construction shown or a substantial equivalent thereof,a device is provided which will be simple and inexpensive, yet will bevery easy to operate and exceptionally well adapted to the purposes forwhich it is designed.

As excellent results may be obtained from the structure disclosed, thisstructure is preferably followed, but within the scope of the inventionas claimed, numerous minor changes may be made.

I claim:

1. A closure operator comprising an operating member and means forpivoting it to a closure frame or other stationary part, a link pivotedat its inner end to an off-center part of said operating member, meansfor connecting the outer end of said link with a closure, and a stopadapted to be mounted stationarily in the lateral path of said link tolimit the movement oi said link to a point slightly beyond dead centerwhen the closure is moved to an extreme position.

2. A closure operator comprising an op erating member pivoted to aclosure frame or other stationary part, said operating member having aseries of notches, a link pivoted at its inner end to an olf-center partof said operating member, means for connecting the outer end of said`link with a closure, and a bolt disposed for engagement with thenotches in said operating member whereby it is held in an intermediateposition and against turning in either direction.

3. A closure operator comprising an operating` member pivoted to aclosure frame or other stationary part, said operating` member having aseries of notches, a link pivoted at its inner end to an off-center partof said operating` member, means for connecting the outer end of saidlink with a closure, a stop mounted stationarily in the lateral path ofsaid link to limit the movement thereof to a point slightly beyond deadcenter when the closure is moved to extreme positions and a boltdisposed for engagement with the notches in said operating memberwhereby it is held in intermediate positions.

4. A closure operator comprising an 0perating disc pivoted to a closureframe or other stationary part, said disc having a series ot peripheralnotches, a link pivoted at its inner end to an off-center part ot' saidoperating disc, and at its outer end to a closure, a stop mountedstationarily in the -10 lateral path of said link to limit the movementthereof to a point slightly beyond dead center when the closure is movedto eXtreme positions, and a bolt disposed for engagement with thenotches in said operating disc 3 whereby it is held in intermediatepositions and against turning in either direction.

In testimony whereof I have hereunto atiXed my signature.

SAMUEL B. CHAFFEY.
